REFRIGERATOR-CAR.

SPECIFICATION' forming part of Letters Patent No. 304,197, dated August26, 1884.

(No model.)

,To all whom it may conce/nf Be it known that I, HUGH F. HOGAN, aeitizenof the United States, residing at Albion, in the county of Noble andState of Indiana, have invented certain new and useful Improvements inRefrigerator-Cars; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference beinghad to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Figure l of the drawings is a vertical longitudinal sectional view of mydevice. Fig. 2 is attransverse section of the same. Fig. 3 is ahorizontal section, and Fig. 4 is an end view. This invention hasrelation to` means for preserving fruit, vegetables, meat, and fish fromspoiling during transportation; and the invention consists in theconstruction and novel arrangement of devices, as hereinafter set forth,and pointed out in the appended claims.

In the accompanying drawings, the letter A designates the bottom of thecar, which is made double, in order to provide an air-space or chamber,b, between the inner and outer floorings, having openings c, for freeinlet and exit tothe air. The cross-timbers D ofthe bottom are extendedlaterally beyond the walls E of the car to support outer side walls, F,between which and the walls E are the lateral air-chambers G, extendingthe heightv of the car from bottom to top,and open at each end, as shownat h. The top K of the ear is double, an air-chamber, L, being providedtherein, extending the full' length of the car, and having air-openingsm in front and rear, covered with wire-.gauze or perforated metal Thetop Ii extends lat erally sufficiently to cover the upper edges of theouter walls, F. rllhe ends I? of the car are also made with outer andinner walls, forming air-chambers S, which are provided with openings t,for the free inlet and exit ofthe air. The inner side walls of the car(shown at E) are made double to provide airchambers V, which areprovided with openings u, covered with wire-gauze or perforated metalplates, to let the air freely in and out. These lateral air-chambers Vshould communicate with the air-chamber L in the top of the car.

The walls a a of the air-chambers V should be made of light material, inorder that the full benefit of the air-drafts through'thelateral fines Gmay be had. Air-pipes e, protected by wire-gauze or perforated metalattheir ends, are extended through the walls F and E into the car. Exitspouts or openings to permit the escape of waste water are provided inthe bottoms of the air-chambers V at each end. Within the hollow walls Eare provided ledges g, in vertical succession at different heights, asshown, to serve as bearings for the movable concave or trough shelves B,which extend lengthwise of the car and serve to hold the ice, which ispacked between the walls a a in very hot weather.l Removable panels O,forming portions of the inner wall a, are provided, in order that theinterior of the chambers Vean be easily reached to facilitate theice-packing. The air-chambers S in the end walls may also be packed withice. .The open ends h of the side air-passages, G, are made iiaring, asindicated at z, in order to guide as much air as possible into thesepassages. The inner walls, E, of the ear have doorfopenings Z, andsliding doors are provided to close the same. The outer lateral walls,F, also have door-openings 7c opposite the door-openings Z, and slidingdoors are also provided therefor.

This car is constructed in such a manner as to provide free ventilationthrough its interior andabout its exterior. draft through the lateralflues G whenthe car is in motion causes air to be forced through the earon each side, and is designed to effectually dispel surface moisture onthe articles being transported in the car. A In het weather this air iscooled by packing the chambers of the hollow walls with ice.

Having described this invention, what I claim, and desire to secure byLetters Patent, ist l. In a preservingcar, the combination, with thehollow perforated walls E, having removable ice-troughs in the chambersthere The powerful IOC) of, of air-passages G, extending lengthwise ofthe car exterior to said hollow perforated Walls, as speoiiied.

2. The preserving-ear having the air-chambers b, L, S, and G, the latterhaving flaring openings z at opposite ends of the oar, and the lateraland end chambers having air-tubes e, the chambers S having openings t,the lateral chambers V, having the removable ieetronghs, and therespective chambers having sliding doors, substantially as speoied.

3. Thepreserving-oarhaving open air-chambers in its top, bottom, andends, and hollow side Walls E, in combination with outer side Walls, F,forming, with the side walls E, lat- 15 eral air-passages G, havingflaring openings z at each end and extending from end to end of the ear,and the lateral chambers VV, having the removable ice-troughs,substantially as speoied.

In testimony whereof I affix my signature in presence of two Witnesses.

H. F. HOGAN.
